New to Business Architecture
If you're new to business architecture, this guide will help you understand the core concepts and how the Orthogramic Metamodel makes it practical to get started.
What is Business Architecture?
Business architecture is a discipline that helps organisations understand how they operate, deliver value, and respond to change. It does this by modelling the organisation's structure, strategy, capabilities, information, stakeholders, and more in a way that supports decision-making and alignment.
The Orthogramic Metamodel is a structured approach to business architecture that enables consistent modelling across all these areas. It defines the types of things that should be described—like capabilities, value streams, policies, and organisation units—and how they relate to each other.
An organisation unit represents a sub-division or entity within an organisation that focuses on specific functions, processes, or objectives to contribute to overall goals. These units act as operational or strategic building blocks.
Examples:
- Rail and Infrastructure Division
- Customer Service Department
- Digital Transformation Office
- Finance Team
The Metamodel is designed to be used by business leaders, strategists, analysts, and architects alike. Unlike traditional, narrative approaches, the Orthogramic Metamodel is designed for clarity, reusability, and automation. It is open, digital, and platform-neutral.
What the Orthogramic Metamodel Includes
The Metamodel defines domains—categories of knowledge that help describe how a business works. Each domain is supported by a structured data model (called a JSON schema) to ensure consistency.
| Domain | What it Describes |
|---|---|
| Strategy | The goals, priorities, and strategic drivers of the organisation |
| Capabilities | What the organisation is able to do, independent of how it is done |
| Value Streams | The high-level flows that deliver value to customers or stakeholders |
| Organization | The structure of the organisation, including units and roles |
| Initiatives | Major programs, projects, or changes underway |
| Information | Key data assets and how they are governed and used |
| Policy | Internal rules, controls, and regulatory obligations |
| Stakeholders | Individuals or groups with an interest in or influence over the organisation |
| Performance | Measures and indicators used to track success |
Why Structure Matters
In many organisations, documentation is inconsistent, fragmented, and locked in different formats. The Orthogramic Metamodel provides a consistent structure that allows documentation to be:
- Comparable — Different business units can be assessed using the same approach
- Searchable and analysable — Structured data supports analysis, dashboards, and automation
- Interoperable — Data can flow between tools and teams without manual translation
By using the Orthogramic Metamodel, teams can create a shared language for describing how the business works and ensure that architecture is not a niche technical activity, but part of everyday decision-making.
This "consistent structure" translates directly to benefits you understand:
- JSON Schema validation ensures data quality
- Standard formats enable ETL and integration
- Explicit relationships support lineage tracking
- Machine-readable definitions power automation
Where to Start
You don't need to model everything at once. Start small and focus on areas where better clarity will support better decisions. Good entry points include:
Capabilities
Describe what your organisation does, not how it does it. Capabilities are stable over time and help you link strategy to operations.
Examples:
- Customer Relationship Management
- Safety Reporting
- Asset Maintenance Planning
→ See the Capabilities domain
Organization
Structure your teams into organisational units and roles, and link them to the capabilities they own or use. This provides clarity about responsibility and collaboration.
→ See the Organization domain
Value Streams
Model how value is delivered from start to finish. Value streams help you see the big picture and understand where multiple units collaborate.
→ See the Value Stream domain
Understanding Relationships
Orthogramic doesn't just describe domains—it also describes how they relate. For example:
- A capability may be owned by one unit but used by others
- A policy may apply to a capability or initiative
- A stakeholder may require certain performance outcomes or information access
You can model these relationships directly using artefacts such as:
Inter-unit Domain Relationships
Show how units depend on shared capabilities, information, or services.
→ See Inter-unit Domain Relationships
Strategic Response Model
Define how your business reacts to external or internal triggers such as market changes or regulatory events.
→ See Strategic Response Model
What Makes Orthogramic Different?
| Feature | Benefit |
|---|---|
| Structured schemas | Clear data, easier analysis, and automation |
| Declarative design | Focus on meaning and relationships, not tooling constraints |
| Open and shareable | Creative Commons licence enables reuse and extension |
| Practical modelling approach | Designed to be used by business teams, not just architects |
Getting Started: 5 Steps
- Choose your first domain — Capabilities, Organization, or Stakeholder are good entry points
- Use the schema templates to structure your descriptions
- Model relationships between domains to gain insights into alignment and dependencies
- Share with others to get feedback and build shared understanding
- Use the data — for reviews, planning, performance tracking, or integration with tools
